I'm trying to fix inconsistencies in the panel-simple driver, and this
caught my eyes. MEDIA_BUS_FMT_RGB888_1X24 isn't a correct format for
LVDS panels. MEDIA_BUS_FMT_RGB666_1X7X3_SPWG,
MEDIA_BUS_FMT_RGB888_1X7X4_SPWG or MEDIA_BUS_FMT_RGB888_1X7X4_JEIDA
should be used instead. As I couldn't find documentation for the panel,
I can't tell which format is correct. Could you please help ?
